S1m0ne (2002)
The appearance and fate of the scientist character, Hank Aleno, is identical to the appearance and fate of the scientist who steals the aliens in "Repo Man". Especially noteworthy are the sunglasses with a lens missing, his dissheveled appearance, his muddled speech, and his exposure to radiation/microwave emissions.

Better Call Saul: Marco (2015)
(TV Episode)
During the montage of cons in the season one finale of Better Call Saul, Marco is heard saying "Kid, help me get my wife's car out of this bad neighbourhood." Which is the same line of dialogue spoken by Harry Dean Stanton's character Bud in Repo Man when he cons Emilio Estevez into helping repo a car.
